I need some direction from someone more familiar with the particulars 
of using BitBlt.

In my current project there are 3 forms:
	srcForm
	dstForm
	maskForm
of which scrForm and dstForm are 32-bit depth and the maskForm is 1-bit 
depth.  The maskForm contains black pixels in a non-rectangular shape.

I want to copy pixels from the scrForm onto the dstForm using the 
maskForm for inclusion.  The srcForm is smaller in extent than the 
dstForm.  The maskForm is the same size as the dstForm.  I've tried a 
number of things, and frankly went into this believing it would be very 
simple, but ended up implementing pixel copies.  There must be a 
smarter way.
